Screw Type Sludge Dehydrator Introduction
The screw extrusion dehydrator is widely used in the dehydration of high-humidity slag materials before drying, such as the dehydration of distiller's grains, pomace, medicinal residue, cassava residue, etc. It can remove about 20% of the moisture in the materials and greatly reduce the burden of the dryer. Thus, the output is greatly increased, and the energy consumption is largely reduced. The screw extrusion dehydrator is an indispensable processing equipment for high-humidity materials before drying. After dehydration, the materials can directly enter the drying equipment, which greatly reduces the drying energy consumption.
Screw Press Sludge Dehydrator Features
1. Low energy consumption, small footprint, and physical mechanical extrusion and dehydration
2. Single shaft and double shaft series for your choice.
3. It can realize automatic control
Working Principles
After the speed control motor is running normally, the materials are evenly added from the feeding box. Then the materials are driven by the spiral rotating blade to move forward in the axial direction. During the advance process, the materials are affected by the changing pitch and the adjustment baffle, thus forming a huge squeezing force. Then the materials are mechanically dehydrated under the action of external force. The water is discharged from outlet through the screen, and the dehydrated materials are discharged at the discharge box.
